ALEXANDER MCDONALD, OF GLASGOW, MONTANA.

RAILROAD-LANTERN.

Specification of Letters Patent.

Patented Dec. 22, 1908.

Application filed June3, 1908. Serial No. 436,428.

To all whom it may concern:

Be it known that I, ALEXANDER McDon- ALD, a citizen of the UnitedStates, residing at Glasgow, in the county of Valley and State ofMontana, have invented certain new and useful Improvements inRailroad-Lanterns, of which the following is a specification.

My invention relates to new and useful improvements in railway lanternsby which the same may be used for emitting a light of any color by meansof a translucent curtain which may be pulled down over the flame, suchas red, blue, or any other color which is used in railroading.

With this and other objects in view my invention consists in the novelconstruction and arrangements of parts as hereinafter described andspecifically pointed out in the claims hereunto appended.

Referring to the drawings, Figure 1 is a perspective view of my improvedlantern, showing the curtain in dotted lines. Fig. 2 is a side elevationof my lantern showing the curtain pulled down and secured in position.Fig. 3 is a longitudinal sectional view of the roller-casing, thecurtain and part of the roller being shown in section. Fig. 4 is aperspective view of the lower section of the curtain showing a hookattached thereto. Fig. 5 is a top plan view of the roller-casing and themeans for connecting it to the upper portion of the lamp.

Referring more particularly to the drawings, which are for illustrativepurposes only and therefore not drawn to a scale, the numeral 1indicates the frame of my lantern,

having mounted thereon the cap 3. The

frame-members 2 converge at their lower portions to form a seat 4, as asupporting means for the oil tank 5, said frame-members curvingoutwardly and downwardly into feet 6.

Supported by the recesses 8, cut on the inner faces of the frame-membersare the annular ribs 7. The perforated lugs 10, formed on the upperportion of oppositely disposed frame-members, are for the purpose offorming a means of connection between the said frame and the lowerhooked portion 10 of the handle 11.

The globe of the lantern is of the usual form and is seated in theordinary way. The flame 12 is fed by the usual form of burner 13.

The cap 3 is tapered down to a reduced neck 14 by means of nut and bolt00111100".

tions 18."

The roller 19 (Fig. 3) is rotatably connected in the said roller-casingat one end by an axial. rojection20, which is secured in the end ofpsaidroller, and at the other end by the axial projection 21 which is securedin the roller-casing. A helical or spiral spring 22 is incased in thehole 23, of said roller, one end of said spring being connected to theinner end of the projection 21, the other end connected to the inner endwall of said hole. The translucent curtain 24 is shown wound around saidroller in its normal position.

The strip 25 is secured to the lower edge of the curtain to keep thecurtain spread out and form a substantial connecting means between thecurtain and the hook 26 which is secured to said strip.

In the operation of this lantern the hook 26 is caught by the finger andby the exertion of suflicient force the curtain is unwound from theroller and said hook is inserted in the U-sha edlip 27, thus holding thecurtain down in rout of the flame. It is obvious that in order to rollthe curtain upon said roller, the hook 26 is released from the U- shapedlip 27 and the force of the coil spring 22 rolls said curtain up on saidroller.

Although I have specifically described the combination, construction andarrangements of the several arts of my invention I do not confine myselfparticularly to such specific combination construction and arrangement,as I claim the right to make such changes and modification therein asmay clearly fall within the scope of my invention, and which may beresorted to without departing from the spirit, or sacrificing any of mypatentable rights therein. 1

Having described my invention, what I claim as new and desire to secureby Letters Patent is, I

1. In a device of the character described in combination a lamp; a bandsecured to the upper reduced portion of the cap of said lamp by nut andbolt connections, a section of said band being flattened; aroller-casing having a longitudinalslot cut therein detachably securedto the flattened portion of said band;

a roller rotatably mounted in said roller casing by an axial projectionon one end, secured to said roller, and by an axial projection 21 at theother end, secured to said roller casing; a translucent curtainconnected to said roller and adapted to be drawn down through said slotin front of the flame of said lamp; a hook connected to the lower edgeof said curtain; a U-shaped lip connected to the lower portion of saidlamp and adapted to engage said hook on said curtain.

2. In a device of the character described in combination a lamp; a bandsecured to the upper reduced portion of the cap of said lamp by nut andbolt connections; a section of said band being flattened; aroller-casing having a longitudinal slot cut therein removably securedto said flattened section by suitable fastening means a roller, having ahole in one end, rotatably mounted in said roller-casing by an axialprojection 20, on one end, secured to said roller, and by an axialprojection 21 at the other end, said projection 21 being secured to theroller casing; a curtain connected to said roller and adapted to bedrawn down through said slot infront of the flame of said lamp; a hookconnected to the lower end of said curtain; a U-shaped lip connected tothe lower portion of said lamp and adapted to engage said hook on saidstrip; a helical or coil spring incased in said roller, one end of saidspring being connected to the inner end of said projection 21, the otherconnected to the inner end wall of said hole, said spring providingsuflicient force to revolve the roller in order to wind said curtainupon said roller, when the hook on said curtain is released from saidlip on the lower portion of said lamp.

In testimony whereof I aflix my signature in presence of two witnesses.

ALEXANDER MCDONALD. Witnesses:
